Lets talk about clear lag. The mine-craft plugin programmed to delete entities after a set amount of time. Most people I have talked to find this plugin highly annoying. For people that use mob farms or die from fall damage it is extremely annoying to have all you stuff deleted because you couldn't get back in time to your location of death. The concept for clear lag is pretty decent, but it doesn't really help the server that much. As shown in this image One stack of blocks on the ground counts as 5 entities. One stack of items: counts as 4 entities Also, default mine-craft has built in entity de-spawn of 5 minutes. Meaning that even if clear lag wasn't on the server it wouldn't really hurt the amount of ram needed to run, or drop framed that much in any case.
